Water leaks can cause water bills to rise dramatically. Small leaks typically turn into larger leaks and higher bills if not fixed in a timely manner. The District only allows a water bill leak adjustment once every five years – see form Application for Leak Adjustment Credit.
Do you have a leak?
To determine if you have a leak, you will need to locate your water meter box usually out by the street. Once the box is located, read the meter and write down the read. Do not use ANY water for one to two hours and then read the meter again. If the meter has changed, you may have a leak. Leaks may sometimes be sporadic so this process may need to be repeated.
What to do if you have a leak?
If you have a leak, try to determine if it the leak is located between the house and the meter, in the sprinkler system or in the house itself. To determine if it is in between the house and the meter, turn off your main water valve for the house. If the meter is still spinning, the leak may between the house and the meter. To determine if the leak is in the sprinkler system, turn on the irrigation master valve. If the meter spins, you may have a leak in your sprinkler system. If both of these tests result in the meter not spinning, you may have a leak in your house. Some possible areas to check for leaks are shown below.
